Rheem rrka a030jk08e outside ac fan does not work

If only fan not working, replace capacitor and try. Still problem, you have to replace fan motor itself.

If you mean outside unit not working, check input at thwe out door. If not check your PCB. Repair it.

I have a Rheem Heat and air unit. Model # RGAC-080AW Serial # CM3D104 F4782 4794 and need to find out where the filter for the unit is located.

What filter are you talking about?
Air filter: Usually with a heat and air unit, the air filter is located behind the return air grill.
Return air grill looks similar to ordinary ceiling or floor grill where the hot or cold air blows into each room. Except the return air grill is larger and is usually put close to the heat-air unit.
Remove the grill and replace filter every 3-6 months.
If no filter is present, then dust and hair get stuck on the coils and unit will not meet temperature setting.
See image of typical air filter:

My Rheem RRKA-AO3OJK08E unit froze up, yesterday (frost on tubing). I cleaned the filter, really good, and turned off unit to let thaw. I have not tried to re-start it, yet. Can you tell me the usual...

Either your filter was really stopped up or you could be low on refrigerant. If your filter was stopped up, be sure it is thawed out all the way with no more ice build up, and go ahead and turn it on. You may have already solved your problem. It it freezes up again, you will have to have your refrigerant checked.
The only other thing it could be would be a stopped up evaporator coil. This happens when the unit is ran for a long time without a filter or when the filter doesn't fit in the blower correctly.

Ensure air filter door is seated.

Filter location? Rheem Classic Super Quiet 80, RCBA 2457GG14XI

Open the two side panels. The filter is at the bottom held down with a wire spring. Release the spring and the filter can be removed.

Air not circulating through vents

is the unit running outside? did you check the breaker? Ruud units often times will have a reset bitton on the outside unit to the left of where the freon lines connect. It is a high pressure switch if it comes on when reset make sure the coil is clean and the fan runs(outside)
